The first extended comprehensive data set of the retrieval uncertainties in passive microwave observations of cloud liquid water path (CLWP) for warm oceanic clouds has been created for practical use in climate applications. Four major sources of systematic errors were considered over the 9-year record of the Advanced Microwave Scanning Radiometer-EOS (AMSR-E): clear-sky bias, cloud-rain partition (CRP) bias, cloud-fraction-dependent bias, and cloud temperature bias. Errors were estimated using a unique merged AMSR-E/Moderate resolution Imaging Spectroradiometer Level 2 data set as well as observations from the Cloud-Aerosol Lidar with Orthogonal Polarization and the CloudSat Cloud Profiling Radar.

Satellite sources include SSM/I, TMI, AMSR-E, WindSat, SSMIS, AMSR-2 and GMI.

In a retrospective review, we present the results of operative treatment for six pediatric patients who sustained such injuries while wearing seatbelts. There were three purely ligamentous injuries, two bony injuries (Chance fractures), and one combination injury.

Comparisons of the reductions achieved with posterior Harrington instrumentation of 21 type A and 26 type B burst fractures revealed that the percent correction of angular deformity at surgery was significantly higher (type A, 52% versus type B, 65%) and was better maintained at 6 (type A, 13% versus type B, 36%) and 12 months (type A, 0% versus type B, 28%) after surgery in type B fractures (p less than 0.05). Percent correction of anterior compression achieved at surgery was similar for both groups (type A, 33% versus type B, 37%), but maintenance of correction 6 (type A, 9% versus type B, 23%) and 12 months after surgery (type A, 3% versus type B, 23%) also was significantly better in type B fractures (p less than 0.
